The Hidden Hazards: How Smoke and Ash Transform Swimming Pools

The subsequent instructions pertain to the upkeep of pools affected by smoke, ash, or fire damage. Avoid using the pool until these procedures are fulfilled.

Restoring Water Clarity and Chemistry: Adhere to the eight steps below to restore the pool’s water clarity and chemistry, provided that the recirculation systems, electricity, and safe water access are operational. For pools in the zone of the Do Not Drink Order, do not refill the pool using tap water until the Order is rescinded.

1. Skim the water’s surface utilizing a pool net and clear the skimmer baskets of all debris.

2. Scrub the walls and floor of the pool to dislodge contaminants. Vacuum the pool.

3. Backwash and cleanse the filter(s). Release wastewater exclusively into a municipal sewer. Backwashing into storm drain systems (driveways, gutters, roads, storm drains) is illegal.

4. If required, repeat steps 1-3 after filter cleaning.

5. Evaluate the pH level and modify it to between 7.2 and 8.0.

6. Assess the free chlorine concentration and adjust it to at least 2.0 ppm.

7. Inspect the filter pressure and flow meter to confirm that the recirculation system is operating correctly.

8. Reopen the pool to swimmers only when the drain cover at the deep end is visible, the pH levels are between 7.2 to 8.0, and the free chlorine is at least 2.0 ppm.

A swimming pool service company can be hired to clean the pool. Ensure that they possess a business license and relevant expertise. Pool service companies are forbidden to discharge backwash into the storm drain system.

Deck Cleaning: Sanitize the pool deck and dispose of debris in the trash. Avoid hosing down the deck towards the storm drains. Reduce dust and ashes from becoming airborne by lightly misting the deck. After that, utilize a firm brush or broom to sweep up and discard the debris. A mop and bucket may also be employed for cleaning. Draining Pools:

Draining pools is usually not advisable. If it is necessary to drain the pool, please contact the Department of Public Works’ Street Maintenance and Integrated Waste Management Division for advice by calling (626) 744-7311. Generally, pool water must be dechlorinated to 0.0 ppm chlorine and possess a pH value between 7.2 and 8.0 prior to draining.

Mosquito Breeding: Pools with stagnant water can foster mosquito breeding. During power losses, you may need to manually maintain chlorine levels until the recirculation system is restored. For help with a pool that is breeding mosquitoes, reach out to the San Gabriel Valley Mosquito and Vector Control District at (626) 814-9466.

Damaged Pool or Enclosure: Pools in public and multi-unit residences that exhibit damage to the recirculation system, the shell, or the enclosure must present plans or equipment specifications to the Pasadena Environmental Health Division before commencing repairs. Approval from the Health Department is not mandatory for pools in single-family residences.
